Comparison between the optimal velocity model and the Nagel-Schreckenberg model
最优速度模型与元胞自动机模型的比较研究

The similarities as well as the differences of the optimal velocity model(OV model) and the Nagel-Schreckenberg model (NS model) are compared by both analytical and numerical approaches. By analyzing the rules of both models,we prove that the NS model is a discrete form model of OV model. By numerical simulations,OV model with different parameters and stochastic NS model are compared from two aspects,namely the fundamental diagram and their dynamics under open boundary conditions. The results show that thes...
